WLAN Fundamentals (WBT)
Have you ever wondered how wireless networks work? How a radio signal can be used to carry high-bandwidth data? How it can be possible to secure traffic broadcast over a wireless connection? This course explains these concepts in detail, starting with the bodies responsible for setting the underlying standards, and how 802.11 Wireless Local Area Networks (WLANs) operate. We discuss the Physical (PHY) and Media Access Control (MAC) specifications for 802.11 WLANs, how an RF signal propagates in air in the presence of obstacles, and how to secure the vulnerable wireless signal. This two hour course is appropriate for anyone new to wireless networking and looking to learn the basics, as well as anyone wanting to brush up on a particular topic. This course consists of detailed descriptions of WLAN functionality and behavior.
